This study's main aim is to look at targeted strength training for muscles at the hips. Specifically to consider whether targeted strength training not only effects strength of the specific muscles but also ability to stand on one leg (single leg balance) as well as walking in children with cerebral palsy? This study is a feasibility of method of investigation.

Primary Outcome Measures:
  • Gait parameter [ Time Frame: baseline, plus 8 weeks and plus 8 weeks (exit point) ]
    4 camera CODA gait analysis system for change in percentage stance phase of gait and stride in cm.

Secondary Outcome Measures:
  • Gross Motor Function Measure (GMFM) [ Time Frame: Baseline, plus 8 weeks and plus 8 weeks (exit) ]
    To investigate any change in dimensions D and E of fucntioal activity with standardised GMFM.

Estimated Enrollment: 20
Study Start Date: December 2011
Estimated Study Completion Date: March 2013
Estimated Primary Completion Date: March 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: home progressive resistance exercise Other: Usual care plus progresive resistance training
Duration 8 weeks; two weeks of familiarisation with the intervention protocol without resistance (for familiarisation and neural adaptation) followed by 6 weeks progressive resistance (PR). The three times a week PR training will be as a home exercise program with fortnightly home visits to monitor/progress PR training. It comprises a 4 minute warm up and cool down with one exercise targeting the hip abductors and one the lateral rotators. Exercise prescription will follow existing guidelines for progressive PR training. Parents will be taught supervision by the researcher using clear explanations in words and pictures in a logbook. Logbooks have been found to facilitate compliance, dosage and motivation.
Other Name: strength training

Detailed Description:
This study is focusing on functional change. The reasoning is that if the targeted strength training is effective at improving hip muscle contribution to stability then single leg balance may be improved. This may be functionally evident when weight bearing is taken by say the left leg in gait (percentage stance phase of gait) and as a consequence the opposing swing phase will be optimised as measured by stride. Thus the research question is does strengthening of the rotating and sideways moving hip muscles improve the walking of children with CP as measured by appropriate aspects of gait? Secondly, does this targeted strengthening also increase duration of single leg balance which is a simple easy to use measure in the community without the need for specialised equipment? The primary outcome measure will use a laboratory based 4 camera Codsmotion (CODA) biomechanical analysis system to measure stride (a) and percentage duration of stance phase of gait (b). Secondarily the duration of single leg balance in terms of seconds will be recorded. Gross motor functional and quality of life as also being assessed. The intervention is strengthening which will be implemented with the principles of progressive resistance training. Children with CP's therapists would ask for this type of intervention to be carried out
